SASH-O-PERATINQMECHANISMI SPECIFIGATION' forming part of Letters Patent No. 670,929, dated April 2, 1901;

Application filed July 21, 1900.

To all whom it may concern/.-

Beit known that LEMANUEL FEDE'R,a resident of Cleveland, in the county of Ouyahoga and State of Ohio, have invented, certain new and useful Improvements in Window-Sash- Operating Mechanism; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in mechanism for operating a sliding windowsash, gate, or door.

The invention relates more especially to mechanism that is operatively connected with each side edge of a window-sash and has the arrangement required to accommodate the sliding of the said sash below the window-sill.

The object of this invention is to provide mechanism of the character indicated that is simple in construction and reliable in its operation and that can be conveniently applied and easily operated.

With this object in view the invention consists incertain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings,Figure I is a side elevation showing the lower portion of the window-casing, the window-sill, the window-sash, and my improved mechanism for operating the said sash. Portions are broken away in this figure to more clearly show the construction. Fig. II is an enlarged top plan in section on line II II, Fig. I, and portions are broken away to reduce the size of the figure. Fig. III is an enlarged top plan in section on line III III, Fig. I, and portions are broken away to reduce the size of the figure.

Referring to the drawings, a designates the window-casing, b the window-sill, and c a window-sash that is arranged to slide in a vertical plane at the outer longitudinaledge of the said sill and is slidable below the sill. The outer side edge of each stile of the sash c is provided with a vertically-arranged rack cl, that is fixed to the sash in any approved manner. Each rack d, preferably centrally between the ends thereof, is operatively engaged bytwo pinions e and 6, whose axes are arranged in line horizontally. The said pin-' ionsare operatively mounted upon a horizon- Serial No. 24347. \No models tally-arranged shaft f, that is supported from a bracket g, that projects laterally from and 1 is rigid with the window-casing. The said pinions e and e are arranged far enough apart to accommodate the location between them of a sprocket-Wheel 72, that is operatively said sprocket-wheel h and the adjacent pinions are fixed together in any approved manner-as, for instance, by means of screws '5 (see Fig. 1I)so that the pinionengag'ingh rack cl and connected sash are actuated in in the one direction or the other, according as the aforesaid sprocket-wheel h is rotated in the one or the other direction. Each sprocketwheel h is operatively connected, by means.

of an endless chain j, with-a sprocket-wheel It, (see Fig. III,) that is located at one end of.

and below the window-sill. The sprocketwheel 1:: is fixed upon or operatively connected with a shaft Z, that is arranged horizontally and supported from oneend of a me- I l 1 tallic frame in, arranged below and extending longitudinally of the windowsill at the inner side of the path of the window-sash and suitably secured to the window-casing; Another sprocket-wheel n is fixed upon or opl era-tively connected with the shaft Z and is operatively connected, by means of anjendless chain 0, with a sprocket-wheel 1:), that is operativelymounted upon a horizontally-ar ranged shaft q, supported from the frame below the central portion of thewindow-sill.

There are two sprocket-wheels p and p, that are operatively connected with the different racks, respectively, of the window-sash, and each sprocket-wheel p is interposed between two pinions r and 7*, that are operatively mounted upon the shaft q that bears the said sprocket-wheel, and each sprocket-wheel p and the adjacent pinions are secured together in any approved manner-as, for instance, by means of screws sso thatthe said pinions and sprocket-wheel shall berotated in unison. The pinions r upon each shaft q mesh with the pinions r upon theother shaft q, and one of the said shafts is operatively provided with a crank q for turning the same, and obviously the window-sash c is raised or lowered, according as the said crank is turned in the one or the other direction. The pinions r of each pair of pinions are diametrically larger too y for directly engaging and locking the forward than thesprocket-Wheel p, interposed 'between the said pinions, so that there is no liability of the displacement from the said sprocket-wheel of the chain engaging it.

Preferably the righthand shaft q is provided with the operating-crank, and means pinion of the pinions upon the other shaft q is provided and consists, preferably, of a forked latch t,that embraces a tooth of the said pinion and is pivoted vertically, as at t, to a bracket m, ri id with or formed 11 on the frame m, and a suitably-applied spring 5 acts -to retain the said latch i'nits pinion-locking or operative position. Obviously when the latch t, is in its operative position the window-sash-operatingmechanism cannot be operated by means of the crank q; but the crank and the connected mechanism can only be operated upon rendering the said latch inoperative by swinging it out of engagement With the latch-engagedpinion,and the latch I is provided, preferably, with a knob or handle i to facilitate themanipulation of the latch. v

' It will beobserved that the mechanism here-' inb'efore described is simple in construction 'w, secured tothe said sash in any approved I with pinions'w, operatively mounted upon the I double window." I of the Windo\v,and cu represents the outer and reliable in its operation, does not interfere with the sliding of the'sash helowythe window-sill, and ope rates'equa-l'ly upon opposite stilesuof the sas Figsrll vand III of the drawings show a The sash cis'the inner sash sash that has each stile thereof provided upon-its outerlongitudinaledge with a rack manner, and the racks. to of the sash u mesh shaftsfof the mechanism hereinbfore described. It will be observed,-therefore, that the inner sash andthe outer sashof the double window are simultaneously lowered or raised by means of the one and the same opcrating-crank.

The frame m is slotted, as at m, to accommodate access to the latch 25.

WhatI claim is 1. The combination, with a window-casing and the sliding sash, of two racks secured to the different stiles, respectively, of the sash,

two suitably-supported pinions meshing with each rack, and a sprocket-wheel interposed between thesaid pinions, and the said sprocketwheel and the adjacent pinions having their axes coincident'and being rotatable together, an endless chain engaging the sprocket-wheel at one stile of the sash, another endless chain engaging the sprocket-Wheel adjacent to the other stile of the sash, and mechanism for simultaneously operating the said chains.

2. The combination, with the window-cas i,ng',.the window-sill, and the sliding sash, of

two suitably-supported pairs of pinions arranged below the Window-sill with the pinions of each pair of, pinions in mesh with the pinions of the other pair of pinions,a sprocketwheel interposed between the pinions of each pair of pinions, and the pinions of each pair of pinions and the interposed sprocket-wheel being rotatable together, two endless chains engaging the different sprocket-wheels, re-
